Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit

values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,

damage may occur and reliability may be affected.

*ESD Ratings

ESD Machine Model Protection up to 200 V, Class B

ESD Human Body Model Protection up to 2000 V, Class 2

ELECTRICAL CHARACTERISTICS (Vin = 5.0 V for MAX828 C1 = C2 = 10 mF, for MAX829 C1 = C2 = 3.3 mF, TA = −40°C to 85°C, typical

values shown are for TA = 25°C unless otherwise noted. See Figure 20 for test setup.)
